I doubt it will ever happen. If you look at QueryRewrite(Query *parsetree), the primary entry point to the rewriter, it's easy enough to get a high level overview of what goes on. You can get the post-parse-analyze tree by registering a post_parse_analyze_hook (like pg_stat_statements), and the same tree *after* rule expansion by registering a planner_hook. It isn't obvious what you're missing that a hook into the rewriter would get you. -- Peter Geoghegan http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training and Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
